How long goes a soccer match?

How long goes a Soccer Match?

You are joking? It's 90 minutes of normal time. Each half is (obviously) 45 minutes long but during each half the referee may have to stop play for free kicks, injuries etc so this time is added to the nearest minute at the end.
In some matches if there is a draw extra time is played which has two halves, each being 15 mins long. If the scores are still level penalties may be played.

Hope that was helpful.
By the way Americans, please call it football!
